On certain vehicles, the cup plug which retains the park pawl anchor shaft in the 42RLE automatic transmission could be missing or not properly staked in its bore, potentially allowing the shaft to move out of position and preventing the transmission from being placed in the PARK position. If this occurs and the parking brake is not applied, the vehicle may roll away and cause an accident without warning.
Safety Risk
No risk description available.
Remedy
Dealers will install a bracket to ensure that the park pawl anchor shaft is retained in the proper position.
On certain Dodge Ram 1500 4X4 vehicles equipped with NP246 transfer case, the vehicle's Totally Integrated Power Module (TIPM) contains an incorrect calibration that could potentially result in inadvertent transfer case default to NEUTRAL. If this occurs and the park brake is not applied, the vehicle may roll away and cause an accident without warning.
On certain vehicles equipped with a 3.7L engine and automatic transmission, water from the air conditioner evaporator drain tube may enter the transmission at the fill tube grommet seal. This can result in shudder during torque converter clutch engagement which, if ignored by the operator, could lead to increased transmission operating temperatures, boiling of the water, and a subsequent purging of transmission fluid into the engine compartment that could lead to a fire.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the transmission for leakage at the fill tube grommet seal. If no leak is detected, a new fill tube grommet seal and water deflector shield will be installed, and proper alignment of the fill tube verified. If the presence of a leak is detected, the vehicle will be evaluated for a shudder condition and based on the evaluation, the transmission will either be triple flushed or the torque converter replaced as required and a new grommet seal and water deflector will be installed.
On certain motorcycles, the final drive unit (FDU) oil seal at the drive shaft connection may have been damaged during assembly, causing a leak. If undetected the FDU could run low of oil and seize, which could result in a rear wheel lock-up while riding.
On certain vehicles, the bolts that retain the universal joint to the yoke at the transmission may not be tightened to the engineering specifications. This can result in the drive shaft coming loose from the transmission.
Safety Risk
No risk description available.
Remedy
Dealers will install new bolts at the transmission and, torque to specs the bolts at the interaxle and intermediate drive shaft connections.
On certain vehicles, the retaining bolts that attach the propeller shaft to the center bearing flange and/or the rear differential flange may be missing, not sufficiently tightened or over tightened. If the retaining bolts were to fall out, the drive to the rear wheels may be interrupted. In the worst case, the drive shaft may fall down, increasing the potential for a vehicle crash.
On certain vehicles, a tab on the collar for the planetary gear assembly, an inner part of the automatic transmission, can receive greater force than what it is designed for when the accelerator pedal is operated quickly. This could cause a small piece of metal to be torn from the collar. In the worst case, this small piece of metal may get caught in the parking lock mechanism, causing the parking lock system to be inoperative when the transmission shift lever is placed in the "P" (PARK) position.
Certain operating conditions can result in heat build-up between the countershaft and secondary shaft second gears in the automatic transmission, eventually leading to gear tooth chipping or, in very rare cases, gear breakage can occur. Gear failure could result in transmission lock-up.
Safety Risk
No risk description available.
Remedy
On vehicles with 24 000 kms or less, the dealer will update the transmission with a simple revision to the oil cooler return line to increase lubrication to second gear. On vehicles with more than 24 000 kms, the dealer will inspect the transmission to identify gears that have already experienced discoloration due to overheating. If discolouration exists, the transmission will be replaced. If discolouration is not present, the dealer will perform the revision to the oil cooler return line.
On certain vehicles, the transfer case could, due to changes in the housing casting, allow the oil pump to rotate. Should this occur, oil starvation of the internal gears could result. If this happens and the vehicle continues to be operated, fracture of the transfer case housing can occur.
Safety Risk
No risk description available.
Remedy
Dealer will inspect the housing casting number, and replace the transfer case if required.
On certain vehicles equipped with automatic transmissions, with the forward drive gear selected and the vehicle stationary or in a forward motion, the gearbox could potentially select reverse gear, without indication to the driver.
Safety Risk
No risk description available.
Remedy
Dealers will reprogram the transmission control module.
On certain motorcycles, abnormal wear of certain transmission components could result in a broken retaining circlip. If the circlip breaks, the transmission could lock up, which would also cause the rear wheel to lock up. This could result in loss of control and a crash, possibly resulting in serious injury or death.

On certain vehicles equipped with a Direct Shift Gearbox, a seam at the clutch was not welded to specification. This could lead to degraded performance of the clutch after an indefinite period of use. The clutch could lose its ability to provide input torque to the transmission without prior warning, which could allow the vehicle to roll.
On certain pickup trucks, the transfer case to transmission attaching fasteners may be below the specified torque. This may cause the transmission adapter or transfer case housing to crack and leak fluid. Continued vehicle operation can result in propeller shaft separation and damage to fuel system components, possibly resulting in an underbody vehicle fire.
Safety Risk
No risk description available.
Remedy
Dealer will re-torque the transfer case to transmission fasteners.
On certain vehicles, insufficient tightening torque may have been applied to certain front drivetrain fasteners. Specifically, the affected fasteners are those involving the front differential, the right output shaft housing flange at the engine, and the right-hand engine support. Insufficient torque could lead to a loosening of a fastener. If this happens, at first, noise would be perceptible to the driver. During prolonged driving, sufficient loosening of a fastener could cause damage to a fastener's threading, as well as, to engine and transmission housings. In extreme cases, the right output shaft could become disconnected.
Safety Risk
No risk description available.
Remedy
Dealer will inspect and retighten the drivetrain fasteners to their specified values.
On certain motorcycles, the second/third pinion gear inside the transmission may be incorrectly machined, which could cause abnormal wear that eventually results in a broken retaining circlip. If the circlip breaks, the transmission could lock up, which would also cause the rear wheels to lock up.
Safety Risk
No risk description available.
Remedy
Dealer will replace the transmission gears and shafts.
On certain motorcycles, the hex nut that secures the front drive belt wheel to the gearbox output shaft was torqued to a value less than specification during the vehicle assembly process. As a consequence, the nut could loosen during vehicle operation. If this happens, the belt wheel would itself loosen on the output shaft, resulting in damage to the internal splines of the wheel and to the external splines of the output shafts as the vehicle is operated. Over time, the splines could be damaged to the extent that the output shaft would no longer operate the drive belt, resulting in a loss of drive capability at the rear wheel.
Safety Risk
No risk description available.
Remedy
Dealer will secure the front drive belt wheel to the gearbox output shaft by utilizing a new set of components, including a redesigned front wheel pulley. Also the main-shaft splines will be inspected for proper dimension and replaced is it is out of specifications.
On certain motorcycles, the rear drive belt wheel could crack and eventually fail causing the drive belt to derail. This would result in a loss of drive to the rear wheel. Motorcycles previously repaired under recall 2002185 using the current replacement rear drive belt wheel are also affected. The replacement belt wheels installed for this previous recall may also crack.
Safety Risk
No risk description available.
Remedy
Dealer will replace the drive belt wheel with a wheel that has additional reinforcements (soldering) in the critical deformation zone.
On certain vehicles, the transmission was replaced before being shipped from the assembly plant. This involved removing and reinstalling the propeller shafts. When the propeller shafts were reinstalled, the tightening torque of some of the attaching bolts may not have been to specification. Therefore, there is a possibility that those bolts may become loose.
